One of the best things about "Muppets Most Wanted" is it gives Tina Fey a chance to act like a guest host of "The Muppet Show" for 90 minutes. The "30 Rock" vet/legend plays Nadya, a harsh Russian gulag officer (with a very Boris-and-Natasha accent) who has a special place in her heart for Kermit the Frog. She might be part of the reason there's a rift between Kermit and Miss Piggy at the moment

We chatted with Fey about her favorite Muppets, the episode of television she's seen the most times, and the first time she ever watched sketch comedy on TV. 

"Muppets Most Wanted" is out March 21.
